O2 sending text msg to my email inbox as an attachment?

[Anonymous]

Got this weird email from o2 saying:

Hello,

Here's a picture message you've been sent from ***********.

You can send a message back from your mobile phone. But don't reply to this
email.

Thanks,

O2

It had a txt file attachment, and no links or anything.  At first I thought it was a spam, but recognised my boyfriend's number, so downloaded the attachment to find it was an ordinary text message from him!  How does O2 know my email address?  Is it some weird bug?

He may have accidentally entered your email address in the "Send To" box when he sent the message. Does he have an iPhone?

He's just put his sim in another phone as he broke his iPhone screen last week.  I don't know if it's a smartphone or just a cheap fill in til he gets it fixed.  He said that when I replied it didn't come up with my name, but came up with a photo of me instead.  He didn't have a pic associated with my name before, and I don't have any linked to my email account, so it's just weird?!

Your picture could be syncd from Facebook or from your Gmail account etc.

I know, that's why it's weird because I don't have facebook or gmail!

Yeah, most strange then. Would help maybe if we knew what phone he was using and how he has syncd his contacts to it....?
